READ AND UNDERSTAND THE OPERATORS INSTRUCTION MANUAL THOROUGHLY
BEFORE ATTEMPTING TO OPERATE THIS EQUIPMENT.
Death or serious injury could occur if this machine is used improperly.
Extreme care must be taken when operating electric
models with water present: Ensure power cord is prop-
erly grounded, is attached to a Ground-Fault-Interrupter
(GFI) outlet, and is undamaged.
• Check all electrical cables - be sure connections are tight and
cable is continuous and in good condition. Be sure cable is
correctly rated for both the operating current and voltage of
this equipment.
• Improper connection of the equipment-grounding conductor can
result in a risk of electric shock. Check with qualied electri-
cian or service person if there is any doubt as to whether the
outlet is properly grounded. Adhere to all local codes and
ordinances.
• NOTE: In the event of a malfunction or breakdown, grounding
provides a path of least resistance for the electric current to
dissipate. The motor is equipped with a grounded plug and
must be connected to an outlet that is properly installed and
properly grounded. DO NOT modify the plug provided on the
motor. If the plug does not t the outlet have a qualied electri-
cian install the proper receptacle.
• Switch motor OFF before disconnecting power.
• Engine exhaust from this product contains
chemicals known to the State of California to
cause cancer, birth defects or other reproduc-
tive harm.
• Gasoline is extremely ammable and poisonous.
It should only be dispensed in well ventilated areas,
and with a cool engine.
• Small gasoline engines produce high concentra-
tions of carbon monoxide (CO) example: a 5 HP 4 cycle
engine operation in an enclosed 100,000 cu. ft. area with
only one change of air per hour is capable of providing
deadly concentrations of CO in less than fteen minutes.
Five changes of air in the same area will produce noxious
fumes in less than 30 minutes. Gasoline or propane pow-
ered equipment should not be used in enclosed or partially
enclosed areas. Symptoms of CO poisoning include, head-
ache, nausea, weakness, dizziness, visual problems and
loss of consciousness. If symptoms occur - get into fresh
air and seek medical attention immediately.

Safety Guidelines
Eye and ear protection must be worn at all times when this machine is in use. During normal use,
sound levels exceed 85dB. Use only ANSI approved safety glasses to help prevent eye injury. Every-
day eyeglasses have only impact resistant lenses; they are NOT safety glasses.
Operator must wear appropriate clothing and footwear. Do not wear loose clothing or jewelry that can get
tangled or caught in moving parts. Steel toe safety shoes should be worn.
• Maintain the machine in safe operating condition with all guards in place and secure, all mechanical fasteners
tight, all controls in working order and the machine congured for the job application. Be sure all safety decals can
be clearly read and understood. Replace damaged or missing decals immediately.
• The CPL-8, CPM-4-8 & 10 Planers are designed to plane at, horizontal concrete or asphalt slabs. They
may be called Planers, Mills, Grinders or Scariers and may be equipped with gasoline, propane engines or
electric motors. They are designed to be operated by a single operator from a position at the rear of the equip-
ment.
• Keep a safe operating distance to other personnel in the area and never leave the machine running unattended.
• Avoid deck inserts, pipes, columns, openings, electrical outlets, or any objects protruding from slab surface.
• Never operate this machine while under the inuence of drugs, alcohol or when taking medications that impair the
senses or reactions, or when excessively tired or under stress.
For Electric Models:
Electric motors must be properly grounded at all times. Check the outlet box to be sure the electrical
service is properly grounded. Be sure adequate power is available. Insufcient power will cause a
motor to overheat and burn out.
Use only grounded extension cords correctly sized for the current
draw and voltage drop (amp rating and length). Never use frayed, damaged, taped or under rated
extension cords. Electrical shock could result in death or serious injury to the operator and damage to
the equipment.

When using Hi-carbon steel or Tungsten Carbide cutter wheels:
IMPORTANT!
Read the engine manufacturer’s manual, familiarize yourself with engine start procedures.
3. Check level of oil in engine crankcase (engines are usually shipped dry, oil must
be added as per engine manufacturers instructions). *
4. Check fuel level ( follow engine manufacturers instructions). *
5. Be sure all guards (belt, motor, cutter wheel) are in place and secure.
6. Vacuum hose port should have hose attached or cap installed to control dust
generated during the cutting operation.
7. Locate engine on/off switch, if the engine is so equipped. On some engines the
throttle control is also the engine shut-off switch. Familiarize yourself with this
operation. *
8. All EDCO gasoline engine operated planers are equipped with a STOP switch,
usually located on the handle. Use this switch for emergency engine shut-off. *
9. Cold engine starting: Be sure fuel line valve is open. Set choke (separate lever
on some engines - others have choke as part of throttle control). Open throttle
(full to engage choke) 3/4 to full on engines with a separate choke. Turn engine
ignition switch ON. Be sure emergency STOP switch is ON. *
10. Before starting determine that the recoil starter assembly turns freely, starter
rope pulls easily and the rope retracts properly. *
BEFORE STARTING THE ENGINE: *Gasoline models only
Be sure that the cutter drum assembly has been properly installed and the cutter
drum shaft is in place and secured.
1. Select a level place at the job site. Set the “disengage lever” in the full DOWN
position. Refer to (Figure A).
It is most important to determine the position of the cutter wheels as they relate to
the slab or oor surface. If the drum assembly is lled with cutters, the cutter
wheels will most likely contact the slab when the “disengage lever” is lowered.
Refer to (Figure B).
Turn the “depth adjustment crank” UP until the cutter wheels are clear of the slab.
Refer to (Figure A). Follow these instructions each time before the engine is
started to prevent accidental damage to the slab.
2. Raise the “disengage lever” to the full UP position. DO NOT force the lever. If
resistance is felt, turn the “depth adjustment crank” DOWN one or two turns.
This will allow the “disengage lever” to reach its normal full UP position. Refer to
(Figure C).

Before Starting the Machine:
• Perform a visual inspection of the entire machine and all daily maintenance according to the Maintenance
Schedule on page 19.
• Locate and be familiar with all engine/motor and operating controls .
• For Gasoline models, obtain the Engine Manufacturer’s Owner’s Manual. Read it and understand it before con-
tinuing. Follow the engine manual for break-in instructions.
• Use the correct cutters for the job. Be sure cutter drum is balanced, the number, size and type of cutter wheels
are correct and the cutter drum shaft is locked and secured.
• Be sure all fasteners are tight and secure, check for signs of metal cracking or fatigue, inspect for damage to
electrical wiring, damage to fuel lines, check bearings, etc.
• Be sure all guards are in place. Do not operate unless cutter drum guard is in place and secure.
• Inspect work area to determine the presence and location of deck inserts, pipes, columns and objects protruding
from the slab surface so that they may be avoided during operation.
Starting the Engine/Motor:
For Electric Models:
• Be sure the “ON/OFF” rotary cam switch is in “OFF” position.
• Hook up the correct voltage/phase electrical power source by plugging into the connector provided.
If the cord does not mate with the connector, consult a qualied licensed electrician before continuing.
• Verify that the electrical current being supplied is the proper voltage and phase required to run the equipment.
• Check motor rotation. Cutter drum rotation on the model CPM machines is “down cut.” DO NOT use if drum
rotation is incorrect - have a qualied electrician make the necessary change in the main control panel or motor
connection box.
For Gasoline Models:
• Consult the Engine Manufacturer’s Owner’s Manual and follow the directions
for starting the engine and allow the engine to warm up.
Lanyard Kill Switch (CPM-10 Only):
• The CPM-10 comes equipped with a lanyard kill switch. The operator should attach
the snap hook around his wrist or to his belt. If control of the machine is lost the hook
will pull free and release from the stop switch, immediately stopping the machine.
DO NOT operate gasoline/propane
powered equipment without adequate
ventilation. Carbon monoxide is an
invisible, oderless gas that can kill.

CUTTING
Starting the Cut:
• Slowly lower the cutter head to the slab surface with the cutter head lever.
(Figure 2, Item 1) & (Figure 4)
• Lift the knob of the Depth Control to unlock and turn the hand wheel slowly
until the cutter head contacts the slab (you will hear the sound of the cutter
wheels contacting the slab). Continue adjusting the depth of cut until the
desired depth is reached; max depth of cut 3/8” (9.5 mm).
• Use an Industrial Vacuum Dust Control System for dry planing operations.
• Optional water hookup also available.
To Stop Cutting:
• Move cutter head control lever to raise cutter head assembly above slab surface.
• For gasoline and propane models, close throttle and turn the ignition switch to the “off” position.
• For electric models, depress the “OFF” button.
After Cutting:
• At the end of the day, clean the entire machine after it has cooled. Check for worn or damaged cutters and per-
form any required maintenance. See Maintenance Schedule page 19 and Instructions on page 17.
• If water was used for dust control - - - clean slurry under machine before it drys.

Cutting Heads / Drums:
• Drum assembly revolves at approximately 1200-1800 R. P. M.; Model CPM-10 is a “down-cut” planer, Model
CPM-8 is a “down-cut” planer, and ScariLite-8 is a down-cut planer, Model CPM-4 is an “up-cut” planer. Depth
of cut is completely determined by the material to be cut, horsepower of the engine/motor and spacing of the
cutter wheels on the cutter head.
• All cuts should be started from a stationary position - when the cutting depth is reached the planer should then
move forward.
• The engine/motor should not labor. Run at full speed and adjust forward speed to t the work being performed.
Very hard concrete will have to be cut at a slower pace than asphalt or deteriorated surfaces.
• If it is necessary to make deep cuts - make several shallow cuts to achieve the desired depth. If the cutting depth
is set too deep the cutter wheels will not be able to absorb the shock and damage to the equipment will result.
• The cutter wheels have an oversized arbor hole. This “play” is needed to absorb some of the shock of the cutter
contacting the concrete and allow the cutter to “rebound” from the surface.
• Cutting speed is directly proportional to the amount of material to be removed in one pass; an example - cutters
spaced on 1” centers will penetrate to a greater depth than those spaced at 1/2” centers, and the planer will
move forward faster. Most of the material in the path of the cutting head will be removed either by the cutters
them selves or through the natural hammering action and spalling of the material being cut. A later pass with
cutters spaced closer together will remove the ridges.
To Reach Maximum Depth in Concrete:
• It is best to make several passes - increments of 1/32-1/8” or even less if surface is extremely hard.
• Use coarse (wide spacing) for initial passes. Complete job with medium spacing. Never use a ne spaced cutter
head to cut deeper than 1/32-1/8”.
• Some concrete slabs, especially if they are covered with water a good deal of the time or if they have been treat-
ed with hardeners, develop an extremely high surface strength.
• Material removal depth should not exceed 1/32-1/8” per pass thus requiring several passes to reach the desired
depth of cut.
To Cut Asphalt:
• This surface can be easier to penetrate than concrete. In some instances depths of 1/4” per pass can be
achieved with the larger machines. In general though, 1/8” per pass is still standard and should be maintained
until the hardness of the asphalt is determined.
Note: Specic information on asphalt cutting is available upon request.
Fine Cutting:
• This assembly should be used for very shallow or cleaning operations. Check with dealer for special cutter
wheels for removal of paint build-up or similar surface coatings.

1. Remove plastic plug from belt guard, set aside for later use.
2. Use a socket wrench to loosen left-hand thread retaining nuts. Be sure the socket is over the outer retaining nut
only. The outer retaining nut has to be loosened rst and removed, then remove the second retaining nut. Use
drift pin to hold the other end of the shaft during this procedure.
3. Be careful not to damage threads on end of shaft when removing or installing the drum. Support the weight of the
drum to minimize the possibility of damage.
4. With the left-hand thread retaining nuts removed, use a drift pin to turn the other end of the shaft in a clock-
wise direction for removal. Support drum during shaft removal so the drum will not fall when the shaft is removed,
possibly causing damage to machine and personal injury.
5. Once the drum is removed, maintenance and/or cutter replacement can be performed.
6. Reverse this procedure for reassembly insuring the drive studs are lined up with drive holes in drum before insert-
ing the main shaft. Be sure to install plastic plug removed in step #1.

FOR YOUR SAFETY AND WELL BEING
DRY PLANING
DO NOT operate gasoline/propane
powered equipment without adequate
ventilation. Carbon monoxide is an
invisible, oderless gas that can kill.
Dry Planing:
Dry Planing creates a large volume of airborne dust. For health reasons, the
operator should wear an applicable respirator. The dust may contain chemicals
known to cause serious illnesses, including Silicosis a fatal disease of the lungs.
Check the chemical properties of the material to be removed and follow all
EPA/OSHA regulations.
• An Industrial vacuum, capable of handling high volume of ne dust, such as the
VAC-200 (Figure 5), should be used when dry planing with this machine. If the material
being used is hazardous or contains Silica - the vacuum unit should be capable of
removing Respirable Silica and hazardous particles of less than 3 microns and if
necessary, have the capability to be equipped with a HEPA lter.
• Most standard drum type units use a paper bag lter. The dust created during
planing is extremely ne and will clog the lter bag of these units and eventually
damage the vacuums motor. In addition, damage to the CPM-4-8-10 engine could
occur.
• The collected debris and lters should be disposed of according to procedures that
comply with current EPA/OSHA standards.

EQUIPMENT DEVELOPMENT CO., INC.
The CPL-8-CPM-4-8-10 EDCO concrete Planers were
designed to remove material from the surface of concrete
slabs. The material may consist of excess concrete, coatings,
contaminants such as industrial debris, sealer, paint,
production line spill and virtually any foreign substance that
creates a safety or health hazard on walks, passageways
or oor surfaces.
The EDCO planers are primarily used for surface preparation
in commercial and industrial buildings. The machine’s total
weight is an advantage when used on upper oors where lbs
per sq. feet is an important factor. We have kept the overall
width to less than 36 inches (91 cm) to allow for passage
through most commercial doorways.
Since the maximum depth of cut is 1/2” (2 cm) in increments
of 1/32” to 3/16”, it is not suited for removal of very hard
concrete such as the kind found on roads, bridge decks or
runways. This work is best accomplished by heavy duty
milling machines built for that purpose.
The basic mechanical structure consists of a fabricated steel
frame, a power source - electric, gasoline, or propane (an air
motor can also be adapted), and a rotating drum like cutter
head that can be raised or lowered to a chosen depth by
the operator.
The CPM-4 model is designed with an “up-cut” rotation of
the cutter drum assembly, consequently a milling type action
occurs. The CPM-8, CPM-10 and CPM-8 are down-cut
machines.
The push units require very little manual labor to operate -
the operator controls speed, forward and reverse directions.
Note that it will cut in forward or reverse directions.
The 4” to 10” inch wide drum assemblies consist of a welded
cage holding 4, 6 or 8 hardened shafts - locked in place during
operation and removable when replacing cutters.
Several styles and sizes of cutters are available. All types of
cutters may be used on all sizes of drum assemblies. Cutters
vary in size - 2 3/8” for light removal, 3” diameter for longer
life. Additional cutter wheel specications can be found on
literature and price lists.
The efciency of the planer is determined by 3 factors - the
hardness and type of surface to be removed, the type of
cutting tool and the power behind the cutters.
What to Expect from your
CPL-8 , CPM-4, CPM-8, CPM-10 EDCO Concrete Planer
Since the hardness of the surface cannot be changed
and the cutter type is limited to present state of the art
material and the power source is xed - there may be
conditions that are beyond the capability of the planer.
To exceed these limits will only cause problems. Cutter
life will be shortened drastically, excessive vibration will
most likely cause the scarier to self destruct.
EDCO cannot accept responsibility if the conditions found
on the job site exceed the ability of the equipment to meet
the contractors expectations. It is the obligation of the
purchaser, user or renter to determine the compatibility
of the planer with the job to be performed.
We at EDCO are prepared to assist the user. We can
provide technical information and comparison data
on jobs of a similar nature. Given information on the
project we can advise the contractor which tools, in our
opinion, will suit the job best, approximate production
rates and possibly arrange a demonstration or suggest
an alternative method or equipment.
EDCO concrete planers, when properly used, will perform
efciently and economically, but as with all “demolition”
equipment, unless proper maintenance is provided they
tend to wear out faster than other mechanical devices.
It is important that each job be considered individually.
Testing should be carried out and a determination made
if the project is feasible under the circumstances. In
those instances where no other alternative is available,
various changes in procedure can be tried - shallower
cutting depth, slower forward speeds, spacing of cutters
changed - extra weight added. We do not guarantee
life of cutters, depth of cut, life of equipment (except for
workmanship). Equipment of this type is capable of self
destruction through misuse or abuse and the owner/
operator is the vital component that can mean success
or failure of the project.
Our technical information has been obtained from years
of experience on all types of job sites and we will gladly
share this information with you. New materials are
constantly being introduced - concrete is made harder
with additives, chemicals and new curing techniques. We
try to keep up with these changes, it’s a never ending job
for us and we need your cooperation to provide us with
accurate job site conditions and information.

Grinding/cutting/drilling of masonry, concrete, metal and other materials can generate dust,
mists and fumes containing chemicals known to cause serious or fatal injury or illness, such
as respiratory disease, cancer, birth defects or other reproductive harm. If you are unfamiliar
with the risks associated with the particular process and/or material being cut or the composition of the tool
being used, review the material safety data sheets and/or consult your employer, the manufacturers/suppliers,
governmental agencies such as OSHA and NIOSH and other sources on hazardous materials. California and
some other authorities, for instance, have published lists of substances known to cause cancer, reproductive
toxicity, or other harmful effects.
Control dust, mist and fumes at the source where possible. In this regard use good work practices and follow
the recommendations of the manufacturers/suppliers, OSHA/NIOSH, and occupational and trade associations.
Water should be used for dust suppression when wet grinding/cutting/drilling is feasible. When the hazards from
inhalation of dust, mists and fumes cannot be eliminated, the operator and any bystanders should always wear
a respirator approved by NIOSH/MSHA for the material being used.
Grinding/cutting/drilling of masonry, concrete and other materials with silica in their composition
may give off dust or mists containing crystalline silica. Silica is a basic component of sand,
quartz, brick clay, granite and numerous other minerals and rocks. Repeated and/or substantial
inhalation of airborne crystalline silica can cause serious or fatal respiratory diseases, including silicosis. In addition,
California and some other authorities have listed respirable crystalline silica as a substance known to cause
cancer. When grinding/cutting/drilling such materials, always follow the respiratory precautions mentioned above.

• On new equipment, and after replacing a set of belts, they should be re-tensioned after the rst four hours of use.
• New belts will be stiff and will loosen with use. Proper belt tension must be maintained to transmit the engine/motor
power to the cutting drum. Slipping belts will overheat, belt life will be shortened and the cutting speed limited.
Over tensioned belts will shorten belt and bearing life.
• Damaged, stretched or excessively worn belts should be replaced with a complete set. DO NOT mix new and used
belts, doing so will only shorten the life of new belt(s) and limit power transfer from the engine/motor to the cutting
drum. This will have a denite impact on machine efciency and production rate.
• To tension belts, loosen motor mounting hardware slightly. Use the jacking bolt to adjust the engine/motor until the
belts are tight. Tighten the engine/motor mounting hardware.
Belts:
• Check oil level before operation. Change engine oil and lter according to engine manufacturers recommenda-
tions.
• Clean air lter element daily.
Important!
Figure 8
Engine Air Filter:
• Inspect the air lter (Figure 8) for excess dust, dirt or dam-
age before the engine is operated. More often if operating
in a extremely dusty environment.
• Operating the engine with a damaged or dirty air lter, or
without an air lter, will allow dirt to enter the engine causing
premature engine wear which is not covered under the
engine manufacturer’s warranty.
• Follow the engine manufacturer’s procedures for keeping
lters in good condition.
